CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 561,237, dated June 2,1896. Application filed April 15, 1896. Serial No. 587,714. (No model.)

. To all whom it may concern:

Be it known that I, CHARLES PARKER, a citizen of the United States,residing at Monroe ville, in the county of Huron and State of Ohio, haveinvented certain new and useful Improvements in Oar-Couplers andl dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to certain new and useful improvements incar-couplers, and especially to the type of gravity-pin-supportcouplers, in which the coupling-pin is held on a spring-actuated slideheld within the end of the draw-head and so arranged that when thedraw-heads come together the slide is caused to be forced in, allowingthe coup- 'ling-pin to fall through an aperture in the draw-head andthrough the opening in the link.

A further part of the invention resides in the peculiar manner ofholding an extended end of the coupling-link within the draw-head, whichconsists in forming an integral down wardly-turned hook on the draw-barprovided with a key at its lower end, which is inserted in place afterthe eye in the end of the pro jecting portion of the link has beenplaced over the said hook to securely lock the link in place.

To these ends and to such others as the invention may pertain the sameconsists, further, in the novel construction, combination,

and adaptation of the parts, as will be here" inafter more fullydescribed, and then specifically defined in the appended claims.

I clearly illustrate my invention in the accompanying drawings, which,with the letters of reference marked thereon, form a part of thisspecification, and in which drawings similar letters of referenceindicate like parts throughout the several views, in which- Figure 1 isa central vertical longitudinal sectional view through the coupler. Fig.2 is a View in section, taken on a plane at right angles to thesectional view of Fig. 1. Fig. 3 is an end elevation of a car equippedwith my improved automatic coupler.

Reference now being had to the details of the drawings by letter, Adesignates the drawbar, and is provided with offsets near its forwardend, as seen at B B, and these offsets are slidingly held in therecesses o in the side walls of the draw-head C. The inner end of thesaid draw-bar has a downwardlyextending integral hook A, having anaperture a at or near its end. The linkE has an integral extension 6with an aperture Eat its end, which aperture is provided to receive thehooked end a of the draw-bar. To lock the said hook to the link, the endcarrying the hook is raised in the recesses c, and after the end isinserted through the aperture E in the end of the extension of thecoupling-link the key G is placed in the aperture in the end of thehook, thus locking the draw-head, drawbar, and link. An aperture K isprovided in the draw-head, and in which the hooked end of the draw-barfreely works when it is desired to remove the link.

The means for holding the pin in position to be dropped by gravity toeffect the coupling consists of the plate M, working in a re cess m inthe draw-head, and is spring-actuated by means of the spring N, seatedin the inner widened end of the said recess. An aperture M allows thepin Q to drop by gravity, when the coupler on the end of the car to becoupled comes in contact with the end of the slide M and forces it backin the recess, thus allowing the pin to fall through and retain thelink, which latter construction is of common use in the art.

For holding the draw-bar to the frame of the car it may be secured inany well-known way, as by attaching the block R to the car and havingthe two double acting coiled springs S and T, one on each side of thesaid block. Suitable mechanism, as a crank-lever and chain connections,are provided, so that a person can easily effect an uncoupling of thecars without the necessity of his going between the cars.

Having thus described my invention, what I claim to be new, and desireto secure by Letters Patent, is-

1. A car-coupler, having in combination with a draw-bar, the offsets Bthereon, the draw-head having recesses designed to receive said offsets,an integral hook A on the end of the draw-bar, a link held on the saidsion perforated at its end to receive the said hook, and it key forlooking the draw-bar, hook, substantially as shown and described. 10draw-head, and link in place, snbstztntially In testimony whereof Itilix my signature as shown and described. in presence of two Witnesses.
